To all whom it may concern Be. it known that W6 ,JOHN.D. MAUCH: and FRANK. MARTIN, citizens. of the? United States, and residents. of RibfLake, in'the county of Taylor. and State of Wisconsin, have invented anew and Improved Means for Supporting. and: Releasing Betain-ingstakes, of which the following is a full, clear, and exact description...

Ourinvention has reference to devices for supporting and releasing retaining stakes; and the object thereof is to provide a simple, strong, inexpensive and safe device that can be easily secured to the bolsters of a. car.

We attainthe above object by providing a casing h-aving'meanswhereby it can be secured to the bolster of a car, and which is provided with a bolt having lockingmeans. A shoe which carries thestake has means adapted to engage thefcasing and to be secured by the bolt to the casing, with the locking means preventing the accidental dis placement of the shoe from the casing.

The invention consists of the construction;

secured to the side of the casing 10 where and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which like characters indicate corresponding parts in all the views and in which:

Figure 1 is a side elevation of an end of a railway car provided with an embodiment of our invention; Fig. 2 is a section on line 22, Fig. 1, with certain parts broken away to show the details of construction; Fig. 3 is a plan view of Fig. 1; Fig. 4 is a section on line 4-4, Fig. 3; Fig. 5 is an end view on Fig. 4, in the direction of the arrow, with the shoe removed; and Fig. 6 is a perspective view of the shoe.

Referring to the drawings, 7 represents one end of a flat car having the customary bolsters 8. One end of each of the bolsters on the same side of the car receives a fixed shoe 9. The opposite end of the bolster receives a U-shaped casing 10, the bottom of which is provided with longitudinal slots 11 extending parallel to the sides of the U member. The sides of the member 10 are provided with means by which the same are secured to the bolster. Each of the sides of the U-shaped casing 10 is provided with a slot 12, alining with each other, and through which passes a bolt 13 having notches 14 spaced from each other so. as to lregister with the slots 11 provided in the basev of the U-shaped casing 10. The bolt 113is also provided with pins 15 and 16 ad .jacent each end of the bolt and whereby the movement of said bolt in the, casing is limited. The pin 15, when contacting with theside of the casing, brings the notches. 14 in register with theslots 11.

The end of thebolster contacting with the base ofthe casing 10 is cut away so as to .allow the bolt 13 to move freely; also recesses 17 are formed inthe bolster opposite the slots '11. A U-shaped shoe 18 is provided at each side with a hook-shaped extension 19. The extension 19 of the shoe .passes through the slots 11 inside the re cesses 17 of the bolster when the bolt 13 is in position, as shown in Fig. 5. By moving the bolt 13so that the pin 16 contacts with the adjacent side,the shoe 18' is locked to the-casing 10. To prevent the shoe 18 from disengagingitself accidentally from the casingl0, a locking member 20 is pivotally the pin 15 is provided and the width of the member 20 is such as to fit with its extension 21 between the pin and the side when the pin is in the position shown in dotted line in Fig. 5.

The shoe 18 is preferably connected to the bolster 8 by means of a chain 22, the purpose of which will appear hereinafter. The shoes 9 and 18 are each adapted to receive stakes 23. When a load is carried between said stakes on the car, and it is desired to discharge the same, the stakes 23 are made to collapse by causing the extension 21 of the locking member 20 to retract to the position shown in dotted line in Fig. 2, thereby permitting the bolt 13 to move from the position shown in dotted line in Fig. 5 to the position shown in full by forcing the same with any suitable means. This will permit the shoe 18 to drop out from the casing 10 under the action of the load, and the chain securing the shoe to the bolster will prevent 'jthe same from being crushed by the falling oad.

To operate simultaneously the two bolts 13 of the two devices secured to the adjacent bolsters 8, we provide a sliding bar 24L intermediate said bolts. The sliding bar 24 is mounted in bearings 25 secured to the platform of the car; and the ends of said sliding bar bear against the ends of the bolt,

so that when bolt 13, at the left end of the device, is forced, the bolt 13 of theright end of the device is forced to move with it by the medium of the sliding bar 24. It is understood that the locking members 20 are placed in the position shown in dotted line, Fig. 2.

Having thus described our invention, e claim as new and desire to secure by Letters Patent:

1. In a device of the class described, -a U-shaped casing having slots in the base; a shoe adapted to carry a stake having extensions adapted to engage said slots; a bolt in the casing adapted to engage said extensions and thereby secure said shoe to the casing; and locking means for said bolt to prevent accidental disengagement of said shoe and casing.

2. In a device of the class described,-a U-shaped casing having slots in the base thereof and alining slots in the sides thereof adjacent the base; a bolt engaging said side slots and having notches adapted to register with the slots in the base; means for limiting the movement of the bolt in the base;

a U-shaped shoe having hook-shaped extensions at the sides thereof, said shoe being adapted to engage the slots in the base of the casing with said extension when the vented from accidental displacement from said casing.

3. In a device of the class described, a U-shaped casing having slots in the base, a shoe adapted to carry a stake having extensions adapted to engage said slots, a bolt in the casing adapted to engage said extensions and thereby secure said shoe to the casing, said bolt having means whereby it will disengage the shoe from the casing, and locking means for said boltto maintain the same in a position such as to lock said shoe to the casing.

I11 testimony whereof we have signed our names'to this specification in the presence of two subscribing witnesses.
